Smoltz hasn't formally announced his retirement but he has very likely thrown his last pitch. After spending more than two decades with the Braves, Smoltz split 2009 with the Boston Red Sox and the St. Louis Cardinals where he pitched ineffectively. In 15 starts last season, Smoltz went 3-8 with a 6.35 ERA.

But Smoltz is a shoo in for Cooperstown. He's the only pitcher to have won more than 200 games while saving more than 150. Smoltz pitched in the post-season on 14 occasions including last fall with the Cardinals. He was also selected to 8 NL All Star teams, led the NL in wins and strikeouts twice and in saves once. His best season was in 1996 when he won 24 games en route to the NL Cy Young Award.
